- Add header in these *-reference ports.
- Fix a few of pkg-descr by chase the rename.
- Move all PORTREVISION and PORTEPOCH to top with ?=.
- Put USE_X_PREFIX back in, but under REFERENCE_PORT, and remove PREFIX? and
USE_XLIB. This fix ports to use the correct mtree when you change the prefix,
for example:
Incorrect: (Without USE_X_PREFIX)
================================
# cd /usr/ports/x11-toolkits/gtk20
# make -V MTREE_FILE
/etc/mtree/BSD.x11-4.dist
# make PREFIX=/tmp/foo -V MTREE_FILE
/etc/mtree/BSD.local.dist <-- Here...
================================
